The system tray icon will show a red dot when new activity has occurred.
When you see a red dot on the System tray icon and then mouse over the icon, a tooltip will display summarizing if you have a new chat or mention.

I'm required to participate in more than one persistent group chat. The problem is, whether someone is instant messaging me directly, or someone is sending a message in a group chat, there is only one place the notifications show up in the systray. Is there a way to have one systray notification for persistent group chats or select a different color dot or different color flash? My systray notification is flashing at me all day long with the red dot, and most of the time it is not actionable by me, and it is making me miss chats that are directly for me. Please help!!!

The dot on my system tray icon stays red always, even though there are no unread messages. I would really like a dependable visual indicator that I have a new message on the Teams Client (can the icon on the taskbar flash or change color or something)?

Additionally, system tray icons are almost always wrapped off the screen and are not visible without expanding the system tray.

You don't have this for all users. The red dot does not work if the Taskbar appearance (Taskbar properties) has the "Use small icons" option checked. With regular icon size I have observed the dot but the huge icons are too wasteful of space. I therefore have "small icons" set.

Just as many of the others have stated, the problem is the red dot is identical to the "in a meeting" icon status. The icon appearance in regard to availability/status should be wholly separate from when a new message arrives. Frankly, I don't need a red dot telling me I'm in a meeting.

Every IM/chat app I've ever used gives this capability, so its quite a big missing piece of functionality. Its too easy to miss the banner notification, so having a persistent visual reminder of new messages is vital for any IM topol.

This a much necessary feature. Once one disables the pop up notiications, it is necessary to have a visual cue on the tray showing that something new has arrived, preventing us to keep accessing the window to check.

My users are frequently commenting on the fact they don't see messages that have arrived. We have just moved to teams from slack, and this is the #2 issue we have.

For the most part the users work in the Chat tab all day, then if there is a post on a channel its not particularly obvious - I found using @mention to the channel helps, but it would be nice to be able to have more notification options, including sticky systray messages, sound etc.

It seems to I miss a lot of communications because I am not notified by the app. when I go into the app then I see bold text on the conversation. It would be good to have a more pronounce visual like Skype for business the icon flashing and integration to Win 10 notifications.
